Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an auxiliary assembly tool for a medical device handle and an assembly method thereof. Background Art

[0002] With the development of the medical industry, various medical devices emerge in an endless stream, and the functions of medical catheters are constantly upgraded. Therefore, the design structures of the handles of medical devices, especially some catheters, are becoming more and more complex. For example, for a multi-directional bendable catheter, a relatively large number of pull wires need to be accommodated inside the handle to control the bending direction of the catheter through the pull wires. In addition, the handle also needs to have structures for fixing the pull wires, wires or other components. The complex design structure makes the assembly process of the internal parts and the outer shell of the handle cumbersome. Not only does the assembly take a long time, but it is also very difficult to grasp the tightness of the pull wires and it is difficult to achieve precise positioning. In addition, the handle needs to conform to the human hand holding angle and aesthetic requirements, so the handle often has an irregular shape, which also increases the assembly difficulty. Some traditional bendable handles will add structural parts to fix the internal parts and then sleeve the outer shell outside. This method will increase the weight of the handle and increase the operation difficulty of the handle. Summary of the Invention

[0003] The purpose of the present invention is to provide an auxiliary assembly tool for a medical device handle and an assembly method thereof, which can simplify the handle assembly process and improve the assembly efficiency.

[0062] Embodiment 1

[0063] Such as Figure 1 And Figure 13As shown in the figure, a medical device handle auxiliary assembly tooling is used to install the components inside the handle onto the handle housing 54. It includes a connecting piece 10, a front clamping piece 20, a middle clamping piece 30, and a tail clamping piece 40. The connecting piece 10 has a front end and a tail end. The front clamping piece 20 is arranged at the front end of the connecting piece 10 and is used to clamp the front component 51 inside the handle. The tail clamping piece 40 is arranged at the tail end of the connecting piece 10 and is used to clamp the tail component 52 inside the handle. The middle clamping piece 30 is arranged on the connecting piece 10 and is located between the front end and the tail end, and is used to clamp the middle component 53 inside the handle. The connecting piece 10 passes through the middle clamping piece 30 and connects the front clamping piece 20 and the tail clamping piece 40 to form a working platform for installing the components inside the handle. During installation, the front clamping piece 20, the middle clamping piece 30, and the tail clamping piece 40 are respectively arranged corresponding to the front component installation position, the middle component installation position, and the tail component installation position on the handle housing 54. The front component installation position refers to the position inside the handle housing 54 for installing the front component 51, the middle component installation position refers to the position inside the handle housing 54 for installing the middle component 53, and the tail component installation position refers to the position inside the handle housing 54 for installing the tail component 52.

[0064] The front clamping piece 20, the middle clamping piece 30, and the tail clamping piece 40 are fixedly connected into a whole by the connecting piece 10. When assembling the handle, fix the front component 51 at the front end inside the handle to the front clamping piece 20, fix the middle component 53 in the middle section inside the handle to the middle clamping piece 30, and fix the tail component 52 at the tail end inside the handle to the tail clamping piece 40. The positions of the three parts of the front component 51, the middle component 53, and the tail component 52 fixed on the auxiliary assembly tooling are all consistent with the installation positions of the corresponding front component 51, middle component 53, and tail component 52 on the handle housing 54. Since the positions of each part of the components inside the handle have been fixed by the auxiliary assembly tooling, after the wire extends from the main section of the bending control catheter, it only needs to pass through the wire holes on the front component 51, the middle component 53, and the tail component 52 in sequence, and be limited by a fixing piece at the tail component 52. Finally, directly cover one side of the handle housing 54, then remove the front clamping piece 20, the middle clamping piece 30, and the tail clamping piece 40, and cover the other side of the handle housing 54 to complete the assembly of the handle. The whole assembly process is simple and convenient, which can simplify the handle assembly process and improve the assembly efficiency. In addition, it can also avoid problems such as multiple wires being wound and knotted and inaccurate limiting, and can adjust the tension according to the slack degree of the wire.

[0065] In one embodiment, as Figures 2 to 4As shown in the figure, the front clamping member 20 includes a first front clamping block 21 and a second front clamping block 22. The first front clamping block 21 and the second front clamping block 22 are arranged vertically or horizontally. A first accommodation groove 211 is provided on the first front clamping block 21, and a second accommodation groove 221 is provided on the second front clamping block 22. When the first front clamping block 21 and the second front clamping block 22 are connected, the first accommodation groove 211 and the second accommodation groove 221 are butted to form a clamping space 23.

[0066] As Figure 3 shown in the figure, the first front clamping block 21 includes a first front clamping portion 212 and two first platform portions 213. The shape of the first front clamping portion 212 is semi-circular ring-shaped. The first accommodation groove 211 is arranged on the first front clamping portion 212. Both ends of the first front clamping portion 212 extend outward in the horizontal direction to form a first platform portion 213 respectively. There is a screw hole in the middle of the first platform portion 213.

[0067] As Figure 4 shown in the figure, the second front clamping block 22 includes a second front clamping portion 222, a mounting portion 223 and two second platform portions 224. The shape of the second front clamping portion 222 is semi-circular ring-shaped. The second accommodation groove 221 is arranged on the second front clamping portion 222. A rectangular parallelepiped-shaped mounting portion 223 extends vertically downward from the second front clamping portion 222. A hole matching the connecting member 10 is reserved on the mounting portion 223. The mounting portion 223 is connected to the connecting member 10 through the reserved hole. Both ends of the second front clamping portion 222 extend outward in the horizontal direction to form second platform portions 224 respectively. There is a screw hole in the middle of the second platform portion 224. The two second platform portions 224 and the two first platform portions 213 are fixedly connected together by screws.

[0068] The front clamping member 20 is mainly a component for cooperating with and clamping the front end of the handle. The clamping space 23 formed by butting the first accommodation groove 211 and the second accommodation groove 221 can be circular, rectangular, elliptical, etc. Of course, it is not limited to these shapes, and the shape can also be changed according to the actual front-end component 51 of the handle. The first front clamping block 21 and the second front clamping block 22 can be in an up-down structure or a left-right structure. The number of front clamping blocks included in the front clamping member 20 is not limited to two, and can be three or more.

[0069] In one embodiment, as Figures 5 to 7As shown in the figure, the middle clamping member 30 includes a first clamping plate 31 and a second clamping plate 32 which are oppositely arranged, and the distance between the first clamping plate 31 and the second clamping plate 32 is adjustable. The middle clamping member 30 includes two left and right clamping plates, namely the first clamping plate 31 and the second clamping plate 32. The first clamping plate 31 and the second clamping plate 32 are connected by screws, and the middle part inside the handle is clamped between the first clamping plate 31 and the second clamping plate 32. Since the two clamping plates are connected by screws, the distance between the clamping plates is adjustable to adapt to parts of different thicknesses. The first clamping plate 31 and the second clamping plate 32 are both provided with holes through which the connecting member 10 passes to fixedly connect the connecting member 10. On the one hand, the middle clamping member 30 plays a positioning role, and on the other hand, it can support the internal frame of the handle to facilitate the fixing of the wire or other parts.

[0070] Further, as Figure 5 and Figure 7 shown, one end of the second clamping plate 32 near one side of the first clamping plate 31 is provided with a step 321 matching the part to be clamped. The step 321 and the first clamping plate 31 cooperate to form a clamping groove 33 to adapt to the part to be clamped. It should be noted that the middle clamping member 30 of the present invention can be adaptively modified according to the parts or structures inside the handle, as long as it can clamp the middle part inside the handle. The clamping method is not limited to the left-right structure, and can also be an up-down structure. The number of the middle clamping members 30 is not limited to one group, and multiple groups of middle clamping members 30 can be designed according to the requirements of the handle. When there is no part to be clamped in the middle part of the handle, the middle clamping member 30 can be omitted. The main purpose of the middle clamping member 30 is to be able to fix a certain component in the corresponding position inside the handle to facilitate the cooperation and assembly of other components with it.

[0071] In one embodiment, as Figures 8 to 10 shown, the tail-end clamping member 40 includes a first tail-end clamping block 41 and a second tail-end clamping block 42. The first tail-end clamping block 41 and the second tail-end clamping block 42 are arranged up and down or left and right. The first tail-end clamping block 41 is provided with a first receiving groove 411. One end of the second tail-end clamping block 42 is connected to the connecting member 10 through a reserved hole, and the other end is provided with a second receiving groove 421. When the first tail-end clamping block 41 and the second tail-end clamping block 42 are connected, the first receiving groove 411 and the second receiving groove 421 are butted to form an accommodating space 43 with an opening. The tail-end clamping member 40 is provided with a semi-open accommodating space 43 matching the tail part components of the handle, which can not only fix the position of the part, but also prevent the part from rotating.

[0072] As Figure 9 shown, one end of the first tail-end clamping block 41 extends outward to form a first step portion 412, and the first step portion 412 is located on one side of the first receiving groove 411; as Figure 10As shown, one end of the second tail-end clamping block 42 extends outward to form a second stepped portion 422. The second stepped portion 422 is located on one side of the second receiving groove, and the second stepped portion 422 is attached and fixedly connected to the first stepped portion 412. The first tail-end clamping block 41 and the second tail-end clamping block 42 are in stepped misalignment fit and are fixed by screwing. An arc-shaped receiving groove is respectively provided on the first tail-end clamping block 41 and the second tail-end clamping block 42, and the two arc-shaped receiving grooves are spliced to form a receiving space 43 with an opening. The shape of the receiving space 43 is to match the arc structure of the handle tail-end component 52. According to the shape of the handle tail-end component 52, the shape and size of the tail-end clamping member 40 can also be adaptively changed, and the number of tail-end clamping blocks included in the tail-end clamping member 40 is not limited to two.

[0073] In one embodiment, the connecting member 10 includes a plurality of connecting shafts connected in sequence along the axial direction, and the plurality of connecting shafts are coaxially arranged and relatively fixed. Exemplarily, as Figure 11 shown, the connecting member 10 includes three connecting shafts, and the three connecting shafts are respectively connected to the front-end clamping member 20, the middle clamping member 30, and the tail-end clamping member 40. The main bodies of the three connecting shafts can all be rectangular parallelepipeds, which can ensure that each section is on the same horizontal plane. The connecting shafts are inserted and connected between each other, that is, the tail end of the first connecting shaft 11 is a protruding step 111, and the front end of the second connecting shaft 12 is a groove 121 matching the protruding step 111. Pin holes are provided at the corresponding positions of the protruding step 111 and the groove 121 of the two, and inserting pins or screws can prevent the two connecting shafts from shifting. The shape of the protruding step 111 and the groove can be a cylinder with one side cut off (not a semi-circle) to prevent relative rotation of each section of the connecting shaft. Threads are left on the protruding steps at both ends of the first connecting shaft 11 and the third connecting shaft 13, which is convenient for corresponding fixed connection with the holes of the front-end clamping member 20 and the tail-end clamping member 40. It should be noted that the shape of the connecting member 10 in this embodiment is not limited to a rectangular parallelepiped, and it can also be other regular columnar bodies, as long as it is ensured that each section of the connecting shaft is on the same plane after connection. The step and groove structures on the connecting shaft are also limited to the above shapes, and they can also be other irregular or regular shapes, as long as it is ensured that there is no relative rotation between the connecting shafts after docking; in addition, the docking structure between the connecting shafts is not limited to insertion docking, and it can also be threaded connection, snap docking, etc. The number and length of the connecting shafts are not limited either, and can be changed according to the connected clamping members, or one can be used as an overall connecting member. The axial length of the connecting member 10 in this embodiment is fixed by steps and pins and is not adjustable. Multiple specifications or structural adaptations can be achieved by customizing connecting shafts of different lengths. This structure has good stability, is not easy to make mistakes, and is suitable for large-scale production after design is finalized.

[0074] In another embodiment, the connecting member 10 includes a plurality of connecting shafts connected in sequence along the axial direction, and the plurality of connecting shafts are threadedly connected to make the length of the connecting member 10 adjustable. Exemplarily, as Figure 12As shown, the connecting member 10 includes a fourth connecting shaft 14 and a plurality of fifth connecting shafts 15. The number of the fifth connecting shafts 15 is not limited. On the basis of the structure of the above-mentioned connecting member 10, this embodiment eliminates the pin holes. Thread lines are provided on the protruding steps of each section of the connecting shaft, and the grooves are all changed to threaded holes. The connecting shafts can be matched by screwing tightly through the threads. The overall length of the connecting member 10 is controlled by adjusting the length of the protruding step screwed into the groove. During assembly, one of the clamping plates in the middle clamping member 30 needs to be relatively fixed to the connecting shaft to prevent the middle clamping member 30 from shifting. The fixing method of the clamping plate can be glue bonding, screwing tightly, or the clamping plate and the connecting shaft are made into an integral structure. This structure is flexible and convenient, and the length can be adjusted at any time. It can adapt to the assembly of handles with different specifications of lengths, and is suitable for early design and development, as well as the simultaneous production of multiple specifications in small batches.

[0075] It should be noted that the positions and sizes of all the pin holes and threaded holes in the above-mentioned embodiments are not limited and can be changed according to the actual situation. However, the positions of the central holes reserved in each clamping member for connecting with the connecting member 10 from the bottom end need to be kept consistent to ensure that the handle auxiliary assembly tooling is placed horizontally. The processing method of this tooling can be machining, and the materials are not limited to metals or polymer materials.

[0076] The structure of the handle assisted by the handle auxiliary assembly tooling of this embodiment is as Figure 13 shown. This handle is an omni-directional bending control structure, and the bending direction of the catheter is mainly controlled by four stay wires. The clamping parts are all internal parts of the handle. The assembly method of the medical device handle auxiliary assembly tooling is as follows:

[0077] Fix the front-end component in the handle to the front-end clamping member;

[0078] Fix the middle component in the handle to the middle clamping member;

[0079] Fix the tail-end component in the handle to the tail-end clamping member;

[0080] Pass the stay wires in the handle through the front-end component, the middle component and the tail-end component in sequence, and fix the stay wires to the tail-end component;

[0081] Install the handle housing on the front-end component, the middle component and the tail-end component.

[0082] Specifically, when assembling the handle, first use the front clamping member 20 of the tooling to fix the front-end component 51, the middle clamping member 30 to fix the middle component 53. The middle component 53 can be a tension disc and a base disc, and the tail-end clamping member 40 to fix the tail-end component 52. The tail-end component 52 can be a rocker arm support. The positions of all parts are the same as those on the handle housing 54. Since the auxiliary assembly tooling has fixed the positions of all parts, after the wire is extended from the main body section of the conduit, it only needs to pass through the corresponding wire holes on the front-end component 51, the tension disc, the base disc, and the rocker arm support in sequence, and finally be limited by a fixing member at the rocker arm support. This tooling can avoid problems such as multiple wires being entangled and knotted and inaccurate positioning, and can adjust the tension according to the slack degree of the wire. Finally, directly cover one side of the handle housing 54, remove the tooling, and cover the other side of the handle housing (not shown in the figure) to complete the assembly. Figure 13 Only one kind of handle structure is shown, and the structure of the tooling clamping member can be adaptively changed according to different handle structures.
